Izindlela ze-Sintering ze-Powder Metallurgy (i-powder metallurgy sintering)
Izindlela ze-powder metallurgy sintering ikakhulukazi zihlanganisa okulandelayo:
I-powder metallurgykudinga uchungechunge lwezinyathelo zenqubo ezifana nokukhiqizwa kwempushana, ukucindezela, ukucwilisa, kanye nokucubungula ngemuva. Phakathi kwazo, i-powder metallurgy sintering iyinqubo yokwelapha enezinga lokushisa eliphezulu eqhubeka ihlanganisa ama-compact noma imizimba yempushana exegayo ukuze kuthuthukiswe amandla nezinye izakhiwo. Kodwa-ke, ngenxa yomehluko, izindlela ze-powder metallurgy sintering nazo zihlukaniswe ngezinhlobo eziningi.
1. Isigaba samanzi sintering
Uma kunezingxenye ezimbili noma ngaphezulu ku-compact powder, i-sintering ingenziwa ngaphezu kwendawo yokuncibilika yengxenye ethile, ngakho-ke inani elincane lesigaba se-liquid livela ku-powder compact ngesikhathi sokugcoba.
2. Ukunciphisa ingcindezi
Phakathi ne-sintering, ingcindezi isetshenziswa emzimbeni wempushana ukuze kuthuthukiswe inqubo yawo yokuqina. Ingcindeziukuculakwesinye isikhathi kufana nokucindezela okushisayo, okuyinqubo ehlanganisa ukwakheka kanye nokucwiliswa kwezimpushana ukuze kutholwe imikhiqizo ngqo.
3. Ukwenza kusebenze sintering
Enqubweni ye-sintering, ezinye izinyathelo zomzimba noma zamakhemikhali zamukelwa ukuze kuncishiswe kakhulu izinga lokushisa le-sintering futhi kufinyezwe isikhathi se-sintering, kuyilapho ukusebenza komzimba we-sintered kuthuthukiswa futhi kuthuthukisiwe.
4. EDM sintering
Lapho umzimba we-powder ukhiwa futhi ucindezelwe, ugesi oqondile wamanje kanye ne-pulse usetshenziselwa ukukhiqiza i-arc phakathi kwezinhlayiya ze-powder for sintering; ngesikhathi se-sintering, ingcindezi isetshenziswa kancane kancane ku-workpiece, futhi izinqubo ezimbili zokwenza kanye ne-sintering zihlangene.
Okuqukethwe okwethulwe ngenhla yizindlela ezine ezijwayelekile zokucwilisa i-powder metallurgy. Ngalezi zindlela zokugcoba, inqubo ye-powder metallurgy sintering ingaqedwa ngempumelelo. Ngoba, ngesikhathi se-powder metallurgy sintering, izinhlayiya zempushana zibhekana nezinqubo zomzimba namakhemikhali ezifana nokugeleza okuhlangene, ukusabalalisa, ukuncibilika, kanye nokuvuselela kabusha, ukuze umzimba wempushana uphinde uminyene futhi ezinye noma zonke izimbotshana ziqedwe.
Insiza eyengeziwe
